The Quick Read: A line of credit secured by a rental you already own tops out at 70% combined loan-to-value on Lendmire’s wholesale network, needs a credit score of at least 700, and caps at $500,000. It can fund a rental purchase only if the purchase lender accepts borrowed money as your down payment. Two lenders set the rules: the one that opens the line and the one that funds the purchase.
- An investment-secured line stops at 70% combined leverage. A line on your primary home can reach higher, but only at a 720-or-better credit profile.
- The line must be secured by something you already own. You cannot open one on the property you are about to buy.
- Borrowed funds are often accepted for a down payment and closing costs, and commonly excluded from reserves.
- The line’s payment generally stays out of the DSCR on the new loan. It still hits your personal cash flow.
- Subject to lender guidelines, the strongest files clear two tests: enough equity and enough rental coverage.
Key Terms Defined
HELOC: A home equity line of credit, a revolving credit line secured by a property you own.
CLTV: Combined loan-to-value, meaning your first mortgage plus the line, divided by the property’s value.
DSCR: Debt service coverage ratio, which is monthly rent divided by the monthly payment on the loan being underwritten.
PITIA: Principal, interest, taxes, insurance, and any association dues, the full monthly payment DSCR uses.
Reserves: Cash a lender wants left in your accounts after closing, usually counted in months of PITIA.
Draw period: The stretch when you can borrow from the line, followed by a repayment period.
Vesting: How title to a property is held, whether in your own name, a trust, or an LLC.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Which Property Secures the Line?
The answer sets everything else. “Investment property HELOC” gets used for two different products, and the requirements differ sharply between them.
| Factor | Line on your home | Line on a rental |
|---|---|---|
| Collateral | Your primary residence | A non-owner-occupied rental |
| Main risk | Your home backs the rental | Rental backs the debt |
| Network CLTV ceiling | Up to 90% at 720+ only | 70%, no higher tier |
| Credit floor | Lower floors exist | 700, hard floor |
The first product is the more common route for buying a rental, because equity in a long-held home is often the largest pool of cash an investor owns. The second suits an investor who already has a paid-down rental and wants to tap it for the next one.
In both cases the purchase itself closes on a separate loan, often a DSCR loan. That lender decides whether your borrowed cash counts. Lendmire’s piece on HELOC options for buying a rental with home equity walks through the funding choices side by side.
One more limit applies to the home-secured route. Some lines prohibit renting out the home that secures them. If a primary residence might become a rental later, read the occupancy clause in the line agreement first.
What Are the Investment Property HELOC Requirements?
On Lendmire’s network, a line secured by a rental follows a tight, two-tier table. Credit scores of 720 and 700 both reach 70% CLTV, so a higher score buys eligibility rather than extra leverage. Below 700, there is no tier at all.
| Factor | Investment-secured line |
|---|---|
| Max CLTV | 70% |
| Minimum credit | 700 |
| Line size | $25,000 to $500,000 |
| Debt-to-income | Up to 50% |
| Drawn at closing | At least 75% of the line |
| Structure | 5-year draw, 25-year repayment |
| Valuation | Usually automated |
| Title | Individual or revocable living trust |
Lendmire brokers these lines through select wholesale partners. It is never the lender, and every figure is subject to lender guidelines and full file review.
For perspective, market surveys report that lenders often want roughly 20% equity left untouched on an investment property, with debt-to-income in the 40%–50% range, per NerdWallet’s overview of HELOCs on investment property. On this network, the figures are 70% CLTV (30% of value stays untouched) and a 50% debt-to-income maximum.
A few details trip people up:
- Debt-to-income is tested on the full draw. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on the amount you plan to use.
- Most of the line is drawn at closing. At least 75% comes out up front. You pay on that money whether or not you need it, so size the line to the purchase.
- Pricing floats. It moves through both the draw and repayment periods and never converts to fixed.
- Credit review is personal. The network uses a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing, with no rescores.
- Past credit events matter. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history follows a 7-year path, and a deed-in-lieu, pre-foreclosure or short sale follows a 4-year path.
- Valuation is usually automated. Because an investment line caps at $500,000 and full appraisals begin above that size, these lines commonly close with no traditional appraisal. You can request one anyway.
A primary-residence line works differently. Leverage reaches 90% CLTV, and only at a 720-or-better credit profile. Lines above $500,000 are primary-residence only, cap at 75% CLTV, require a full appraisal, and need a credit profile of 700 or better (720 on the 5-year-draw program).
This article calls the two wholesale programs behind these lines the 3-year-draw program and the 5-year-draw program, after their draw periods. The 3-year-draw program pairs a 3-year draw with a 17-year repayment. The 5-year-draw program pairs a 5-year draw with a 25-year repayment. Investment lines run only the 5-year draw structure.
How Much Can You Borrow Against Your Equity?
Combined leverage is the first mortgage plus the new line, measured against the property’s value. A consumer booklet from the CFPB describes the method: take a percentage of the appraised value, then subtract what you still owe on the mortgage.
Run it with percentages. Say you own a rental, and your first mortgage equals 50% of its value. At a 70% CLTV ceiling, the line can reach up to 20% of the property’s value. If your mortgage sits at 60% of value, only 10% of value is left.
That math surprises investors who assume a paid-down rental gives them 80% of value to use. Not on this network. Equity you can actually reach is the gap between your first mortgage and the 70% ceiling, then reduced again by your credit, debt-to-income, and any line cap.
The same method applies to a home-secured line, with a higher ceiling at higher credit tiers. A longtime homeowner often finds that route yields a larger number, which is why it is the more popular source of down payment cash.
The Two Gates
Think of the whole process as two gates. Gate one is the lender that opens the line. Gate two is the lender that funds your purchase. Passing the first guarantees nothing about the second.
Here is the sequence:
1. Open the line first. It needs to be approved, closed, and drawn before you make an offer you cannot back out of. Lenders will not open a line on a property you have not yet bought.
2. Draw into your own account. Move the money into a dedicated account so its source is easy to document.
3. The purchase lender reviews sourcing. It asks whether borrowed funds are allowed, and for which purpose.
4. The new loan is underwritten on its own terms. On a DSCR purchase, that means the rent against the new property’s payment.
5. Close, then plan the exit. Repay the line from cash flow, or refinance the rental to pay it off.
The purchase lender’s view of borrowed funds is where files succeed or stall. A down payment, closing costs, and reserves are three separate tests, and programs treat them separately.
| Pot | Borrowed funds typically |
|---|---|
| Down payment | Often accepted, sometimes capped |
| Closing costs | Often accepted |
| Reserves | Commonly excluded |
Across the network, programs fall into three groups. Some accept borrowed funds outright. Some cap the borrowed share. Some require part of the down payment to come from your own unborrowed cash. A down payment funded entirely by a line can fail on that basis alone, even when the equity and rent are strong.
This is also where the purchase side matters. Most DSCR purchases land at 75%–80% LTV, meaning 20%–25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700+ score. Reserves vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA. Conservative files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.
Does the HELOC Payment Count Against DSCR?
Generally, no. DSCR compares the new property’s rent to the payment on the loan being underwritten. The line’s payment is not part of that ratio. DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines.
Here is the catch. DSCR is not cash flow. Clearing 1.00 means rent covers PITIA and nothing else. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Now add a second payment. If you borrowed the down payment, your real monthly picture includes the new mortgage, the line, and the first mortgage on whatever secures the line. A deal can show strong coverage and still strain you personally.
On coverage levels, 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. A bigger down payment can lift the ratio, but it never erases leverage caps, credit floors, reserve rules, or property eligibility.
Credit works the same way on the purchase side. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Your line needs 700 on a rental, so the purchase loan is rarely the tighter constraint.

Where the General Rule Breaks
The rental sits in an LLC. A line on this network cannot be secured by a property held in an LLC, corporation, partnership, or an irrevocable, blind, or land trust. Title must sit with the individual borrower or a revocable living trust. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead, subject to program terms. That is the sharpest structural difference from a DSCR loan, which can close in an entity.
The property type is off the list. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible for the line. Single-family, 2–4 units, PUDs, townhomes, and condos, including non-warrantable condos, are eligible. DSCR loans on manufactured homes, log homes, and barndominiums are not offered in the network either.
The property is listed for sale. In a handful of states, a property listed for sale in the past 60 days is ineligible for the line.
You hold a lot of debt or properties. A borrower is limited to three lines. An owner of more than 15 financed properties is not eligible.
The exit depends on value. If you plan to refinance out of the line, the rental must appraise high enough to clear both liens at the lender’s cap. A cash-out refinance on a standard rental tops out around 75% LTV, and about 6 months of seasoning is the common expectation. A DSCR loan with a prepayment penalty can also make an early refinance costly, so read that clause before counting on a quick exit. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The line shrinks when you need it. Lenders can freeze or reduce a line if the property’s value drops. A drawn line is not an emergency backstop.
Availability is narrower. These lines are offered only in Lendmire’s 16 full-service states, narrower than its 41-market DSCR footprint, which includes Washington, D.C. Tax treatment can depend on how the funds are used and how the property is held. Borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
The Risks Worth Pricing In
Effective leverage runs near 100%. A line-funded down payment plus a first mortgage on the new rental means you are financing nearly the whole price. You pay interest on all of it.
Your collateral is at stake. As the CFPB explains for HELOCs, you can lose your home if you fall behind. On a home-secured line, your residence stands behind the rental purchase.
Vacancy hits twice. An empty rental still owes its mortgage, and the line still owes its payment. Stress-test the deal with a vacant property before you commit.
Pricing floats and never converts to fixed. Payments can move across both the draw and repayment periods. Plan for them to rise.
One pattern shows up often in files like this. Investors size the line to their maximum equity instead of to the actual down payment and closing costs. Because at least 75% of the line is drawn at closing, an oversized line means interest on cash sitting idle. The cleaner files borrow the number the purchase needs, not the number the ceiling allows.
In practice, these lines suit short-hold or exit-planned deals better than a decades-long buy-and-hold. Because a line has a draw period followed by a repayment period rather than a fixed 30-year amortization, the exit plan matters.
Line vs. Cash-Out Refinance vs. Home Equity Loan
| Option | Collateral | Key trade-off |
|---|---|---|
| Line on your home | Primary residence | Your home backs the rental |
| Line on a rental | The rental | 70% CLTV, 700 credit floor |
| DSCR cash-out refinance | The rental | Reserves, seasoning, one new loan |
| Home equity loan | Home or rental | Lump sum, one fixed draw |
A cash-out refinance on the rental uses DSCR-style underwriting. It typically carries reserve requirements and seasoning, and it replaces your existing loan rather than adding a second one. A line adds a lien and keeps your first mortgage intact.
Neither is better for every investor. Keep a low first-mortgage balance you value? The line preserves it. Want a single loan and rent-based underwriting? Cash-out fits.
Are You Ready? A Short Checklist
Run through these before you apply:
- Do you have a 700+ score if the line sits on a rental?
- After the line, does combined leverage stay at or under 70% on that rental?
- Is the rental held in your name or a revocable living trust, not an LLC?
- Does the purchase lender accept borrowed funds for the pot you are filling?
- Can your real cash flow carry the first mortgage, the line, and the new loan with the rental vacant?
- Does the new property clear the DSCR floor of the program you are targeting, with room to spare? Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
If you miss on two or more, the better move may be waiting a few months or buying a smaller property. A deal that passes on paper but fails your own cash-flow test is not a deal.
Frequently Asked Questions
Can I open a HELOC on the property I’m about to buy?
No. A line needs collateral you already own, and the purchase lender takes the first lien on the new property. Investors who want to pull equity out of a property right after buying it usually look at a cash-out refinance once seasoning requirements are met.
Can the line be my entire down payment?
Sometimes, but it depends on the purchase program. Some accept borrowed funds fully, some cap the borrowed share, and some require part of the down payment to be unborrowed. Reserves are commonly excluded from borrowed sources. Check the purchase lender’s rule before you draw.
Does the line’s payment lower my DSCR?
Generally not. DSCR compares rent to the PITIA on the loan being underwritten, so the line’s payment stays outside the ratio. It still counts in your real monthly budget and in the line’s own debt-to-income review.
Can an LLC-owned rental secure the line?
Not on this network. Title must be held by an individual or a revocable living trust. An LLC-owned rental needs a vesting change, or a DSCR cash-out refinance instead, subject to program terms.
Do the funds have to sit in my account first?
It varies by purchase lender. Some want borrowed money drawn and documented well before an offer, while others treat it as routine. Draw the line into a dedicated account so the source is easy to trace, and ask the purchase lender what it wants to see.
